  • The FCM1 and FCX1 draw about 6uA when not operating. This level of key-off draw will not drain the battery or shorten battery life.
  • A special circuit disables the controller if the battery voltage falls below the normal operating range. This provides protection in locations where high ambient temperature and sunlight can heat a non-running machine above the temperature setpoint.
  • The FC series controllers include internal EMF suppression, and no additional components should be required in normal situations.
  • For simplicity, standard wiring of the FC series controllers does not utilize a separate power wire. The controller uses energy from the fan power wire which draws directly from the battery. For more information see FAQ “How much current does the fan controller draw when the fan is not running?”
  • An optional wire harness is available to connect the controller to the ignition switch. This can be used if conditions may raise hydraulic fluid temperatures above the ON setpoint when the machine is not in use. A switch installed on the controller ground wire may also be used to prevent the controller from energizing the fan.
  • For standard applications, the OFF temperature is 5°F lower than the ON temperature. This prevents the fan from rapidly switching on and off, or short cycling. For example, if the ON temperature is set to 130°F, the fan will turn off once fluid temperature reaches 125°F. This range is known as the temperature hysteresis.
  • Custom settings are available, please contact us for more information.
  • Yes, if total motor inrush (starting) current is less than 70A. Simply connect both fans to the controller output wire.
  • Yes, wiring for other temperature sensors or switches is available. Please contact us for more information.
  • When powered, the LED will flash to alert that the controller is operational.
  • The LED is also used to report oil temperature, error conditions, and the programming setpoint. See the Literature on the Technical Information page for more details.
  • The controllers automatically adjust for 12VDC or 24VDC.
  • Fan motor voltage must match machine voltage.
  • Using the single-button interface on standard controllers makes it easy to adjust from 120°F to 170°F in 10°F increments. Custom options include alternate default setpoints or a preset non-adjustable temperature setting.
  • See the Literature on the Technical Information page for more details.
  • Yes. The output from the controller can be used to activate the solenoid for the fan motor.
  • Yes. The wire from the battery, through the controller to the fan motor, must incorporate a fuse as close to the battery as possible. This protects the wire, controller, fan motor, and battery in the case of a fault in the system. Consult fan motor supplier for wire size.
  • See the documentation on the Technical Information page for more details.
  • We recommend using a safety device to protect the machine in the case of a fan failure. Providing protection from over-temperature operation is standard practice.
  • Yes. If the controller is exposed to water, we recommend using the optional Rain Boot connector cover, part number RBFC. We also recommend the use of dielectric grease on the connector terminals.
  • Sealed wiring connections are also available. Please contact us for more information.
  • Yes, the FC line can be branded and built to your specifications.
    • Custom labeling and part numbering
    • Special wiring kits, housings, or mountings
    • Custom default settings or programming
  • Many other options are available, please contact us for more information.
